How about getting him a DIY traditional crafts kit? Depending on what kinds of crafts and arts he's interested in, you could consider a wood carving kit, leatherworking kit, embroidery kit, or knitting kit. You can find a lot of options online, and these kits usually include all the materials and tools your husband will need to get started.
Alternatively, you could also consider getting him a subscription to a traditional crafts magazine or finding an online class that teaches traditional crafts like woodcarving or pottery. This way he can learn new techniques and gain inspiration for his own projects.
Finally, if he loves going to art museums or galleries, you could consider getting him a membership to a local museum or tickets to an upcoming exhibition that you know he'll enjoy.
Or you can get him a star map with the date when he was born.
